Given that the posts obviously present a hazard to players (see Amos Roberts), can anyone think of a good reason why we dont use American Football style posts in RL? Surely one hazard is better than two.

Hmm, why not put them on the dead ball line too

No.

They provide an oppertunity for skilled/lucky kickers to use the posts for tricky grubbers against them?

IIRC Hunslet had them in the 70's when they played at the dog track behind Elland Road?

well AF started off with rugby posts so why not?

Yes,"New Hunslet", used to be on the cover of their program, too.

The rules of the game still have a note permitting that shape of posts.

shallwe adopt a 10 yard chain as yell?

Haven't they been used by Russian teams in the Challenge Cup?

I look forward to the outrage the first time a kick that is going dead is stopped by single upright on the deadball line that's part and parcel of that post design

The post is a couple of metres back from the dead ball line in that sport, the bend in the upright puts the crossbar directly over the end line in the end-zone.
